Dynamic stability analysis of nanowire-fabricated nanotweezers is examined in this paper using a new nonlinear model. A novel size dependent model based on the strain gradient theory (SGT) and the Gurtin–Murdoch elasticity (GME) is presented for simulating the simultaneous effects of scale-dependent phenomena (i.e. microstructure dependency and surface energies). Moreover, the impacts of rare field gas damping, structural damping, intermolecular force and Casimir attraction are included in the proposed model. An analytical solution is developed for investigating the dynamic instability. It is established that the proposed model exhibit significant scale-dependence effect on the stability characteristics of nanotweezers.
